问题在哪里呢？

public class Solution {
    public int[] TwoSum(int[] nums, int target) {
        
    }
}
int twoSum(int nums, int numsSize, int target)
{
    int i,j;
    int result=NULL;
    for(i=0;i<numsSize-1;i++)
    {
        for(j=i+1;j<numsSize;j++)
        {
            if(nums[i]+nums[j]==target)
            {
                 result=(int*)malloc(sizeof(int)*2);
                 result[0]=i;
                 result[1]=j;
                 return result;
            }
        }
    }
    return result;
}
